Description

Die Erfindung betrifft ein Kältegerät mit einem wärmeisolierenden Gehäuse, welches durch eine Außenverkleidung, eine Innenverkleidung sowie dazwischen eingetragenes Wärmeisolationsmaterial gebildet ist und in welchem ein Kälteraum angeordnet ist, welcher mit in unterschiedlichen Höhenlagen vorgesehenen Zwischenböden ausgestattet ist, welche sich auf Tragteilen abstützen, welche mittels Befestigungselemente in an der Innenverkleidung vorgesehenen Aufnahmen gehaltert sind.The invention relates to a refrigerator with a heat-insulating housing, which is formed by an outer cladding, an inner cladding and heat insulation material entered between them and in which a cold room is arranged, which is provided with intermediate floors provided at different heights, which are supported on supporting parts, which by means of fastening elements are held in receptacles provided on the inner lining.

Es ist bekannt, Innenräume von schrankartigen Möbeln unter Anwendung von durch Tragteile gestützten Tragplatten, Zwischenböden oder gitterartigen Ablagen in einzelne übereinander angeordnete und in Höhe variierbare Fächer zu unterteilen.It is known to divide interiors of cabinet-like furniture using individual support plates, intermediate floors or lattice-like shelves supported by supporting parts into individual compartments arranged one above the other and variable in height.

Dazu sind in überwiegendem Maße anstatt durchgehender, an den Seitenwänden des Innenraums angeordneter Tragleisten einzelne Tragteile in Anwendung. Diese sind entweder in an den Seitenwänden angeordneten einzelnen Aufnahmen einsteckbar oder aber von vertikalen in Seitenwänden über deren Höhe angeordneten, leiterartig gestalteten Aufnahmebändern gehalten. Die letztgenannten sind insbesondere für den Einsatz in Kühlgeräten schlecht geeignet, da für derartige Maßnahmen dessen Innenraum mit aufwendiger Haltemechanik bzw. nicht minder aufwendiger Formgebung ausgestattet sein müßte.For this purpose, individual support parts are used to a large extent instead of continuous support strips arranged on the side walls of the interior. These can either be inserted into individual receptacles arranged on the side walls, or held by vertical holding tapes arranged in side walls above their height and designed in a ladder-like manner. The latter are particularly unsuitable for use in cooling devices, since the interior of such devices would have to be equipped with a complex holding mechanism or a no less complex design.

Aus der DE-OS 38 02 140 geht ein Kühlgerät hervor, dessen Innenbehälter an seinen Seitenwänden Aufnahmen aufweist, in welche seitlich an der Tragfläche von Tragelementen angeformte Zapfen einsteckbar sind, wobei die Zapfen als geschlitzte Spreizzapfen ausgeführt sind, um das Tragelement reibschlüssig in den Aufnahmen zu halten. Um eine Verdrehung der Tragelemente an den Seitenwänden des Innenbehälters beispielsweise beim Einführen der Ablagen zu verhindern, sind diese Zapfen entlang der Tragfläche mit Abstand zueinander angeordnet. Durch eine derartige Verdrehsicherung muß das Tragelement stets eine gewisse Länge aufweisen, um die Aufnahmen am Innenbehälter mit fertigungstechnisch vertretbarem Aufwand anbringen zu können.From DE-OS 38 02 140 a cooling device emerges, the inner container of which has receptacles on its side walls, into which pegs can be inserted laterally on the wing of support elements, the pegs being designed as slotted expansion spigots are to hold the support element frictionally in the receptacles. In order to prevent rotation of the support elements on the side walls of the inner container, for example when inserting the shelves, these pins are arranged at a distance from one another along the support surface. By means of such an anti-rotation device, the support element must always have a certain length in order to be able to attach the receptacles to the inner container at a technically justifiable cost.

Ferner sind aus der DE-OS 39 45 415 und der DE-AS 11 12 265, der DE-PS 10 14 391 und der GB-PS 7 29 887 als Tragzapfen ausgebildete Tragteile bekannt, zu deren Anbringung die Wände eines Kühlgutbehälters mit Durchbrüchen ausgestattet sind. Außer den aus der DE-OS 39 45 415 bekannten Tragzapfen ist den restlichen gemeinsam, daß der Übergang ihres tragenden Abschnitts auf ihrem Befestigungsteil als Flansch ausgebildet ist.Furthermore, from DE-OS 39 45 415 and DE-AS 11 12 265, DE-PS 10 14 391 and GB-PS 7 29 887 supporting parts designed as trunnions are known, for their attachment the walls of a refrigerated goods container are provided with openings are. In addition to the trunnions known from DE-OS 39 45 415, the rest have in common that the transition of their supporting section on their fastening part is designed as a flange.

Der Tragzapfen gemäß der DE-OS 39 45 415 durchdringt zum Zwecke seiner Befestigung die Behälterwand und liegt mit seinem an einer seiner Stirnseiten angeordneten Flansch von außen an der Behälterwand an, mit der er durch Reibschweißen verbunden ist.The trunnion according to DE-OS 39 45 415 penetrates the container wall for the purpose of its attachment and lies with its flange arranged on one of its end faces from the outside against the container wall, to which it is connected by friction welding.

Der aus der DE-AS 11 12 265 bekanntgewordene Tragzapfen weist einen als Bajonettverschluß ausgebildeten Befestigungsteil auf, mit dem der Tragzapfen durch Verdrehen in der Öffnung einer Tragwand lösbar befestigt ist. Die Haltewirkung der Bajonettverriegelung wird dabei zusätzlich durch eine auf dem Befestigungsteil aufgeschobene, am Flansch des Tragzapfens anliegende Gummischeibe unterstützt, die beim Verriegeln des Tragzapfens zusammengepreßt wird, wodurch der Tragzapfen an der Tragwand unverlierbar festgehalten ist.The trunnion known from DE-AS 11 12 265 has a fastening part designed as a bayonet lock, with which the trunnion is detachably fastened by twisting in the opening of a supporting wall. The holding effect of the bayonet lock is additionally supported by a rubber washer which is pushed onto the fastening part and lies against the flange of the trunnion and which is pressed together when the trunnion is locked, as a result of which the trunnion is held captive on the supporting wall.

Die sichere Anbringung eines solchen Tragzapfens an der Tragwand erfordert neben einem zusätzlichen, als Gummischeibe ausgeführten Zwischenteil weiterhin ein Hilfswerkzeug, um die Verriegelbewegung des Bajonettverschlusses ausführen zu können.The secure attachment of such a trunnion to the supporting wall requires, in addition to an additional intermediate part designed as a rubber washer, an auxiliary tool in order to be able to carry out the locking movement of the bayonet catch.

Sowohl aus der GB-PS 729 887 als auch aus der DE-PS 10 14 391 geht ein Tragzapfen hervor, dessen Befestigungselement als Spreizniet ausgebildet ist. Während der in der britischen Patentschrift gezeigte Spreizniet im wesentlichen einen kreisförmigen Querschnitt aufweist, und dadurch den Tragzapfen im Durchbruch einer Trägerwand kraftschlüssig gegen Verdrehung sichert, ist der Spreizniet gemäß der deutschen Patentschrift mit einem im wesentlichen quadratischen Querschnitt ausgestattet, so daß der Tragzapfen im Durchbruch der Trägerwand gegen Verdrehung formschlüssig gesichert ist. In beiden Fällen ist der Tragzapfen in Achsrichtung infolge eines durch das Eintreiben eines Spreizdorns am Spreiznietes entstandenen Hinterschnittes im Durchbruch der Trägerwand fixiert.From GB-PS 729 887 as well as from DE-PS 10 14 391 a support pin emerges, the fastening element of which is designed as an expanding rivet. While the expansion rivet shown in the British patent essentially has a circular cross-section, and thereby secures the support pin in the opening of a support wall against rotation, the expansion rivet according to the German patent is provided with an essentially square cross-section, so that the support pin in the opening of the Carrier wall is positively secured against rotation. In both cases the trunnion is in the axial direction as a result of an undercut caused by the driving in of an expanding mandrel on the expanding rivet in the opening in the support wall.

Allen vier vorstehend beschriebenen Lösungen ist ein erhöhter Montageaufwand, beispielsweise durch einen nachträglichen Reibschweißvorgang, ein Auftreiben eines Spreiznietes oder ein Verriegeln eines Bajonettverschlusses gemeinsam. Außerdem ist es erforderlich, wie bereits erwähnt, die Trägerwand mit Durchbrüchen auszustatten, daß vor allem bei wärmeisolierten Gehäusen, wie es beispielsweise bei Kühlgeräten einen erhöhten Arbeitsaufwand nach sich zieht. Dabei ist dafür Sorge zu tragen, daß die meist in flüssiger Form eingebrachte Isolierung nicht durch den Durchbruch in der Kühlgutbehälterwand in den Kühlraum des Kühlgerätes eintreten kann.All four solutions described above have in common an increased assembly effort, for example due to a subsequent friction welding process, driving open an expanding rivet or locking a bayonet catch. In addition, it is necessary, as already mentioned, to provide the support wall with openings, particularly in the case of heat-insulated housings, as is the case, for example, in cooling devices, with increased workload. Care must be taken to ensure that the insulation, which is usually introduced in liquid form, cannot enter the cooling chamber of the refrigerator through the opening in the wall of the refrigerated goods container.

Ferner ist aus der US-A-45 34 530 ein zur Halterung von gitterartigen Zwischenböden im Innenraum eines Haushalts-Kühl- oder Gefriergerätes dienendes Tragteil vorgeschlagen, dessen Befestigungszapfen in einem Durchbruch der Innenverkleidung des Haushalts-Kühl- oder Gefriergerätes eingesetzte Aufnahmebuchse kraftschlüssig festsetzbar ist. Zu diesem Zweck ist der Befestigungszapfen mit entgegen seiner Einsetzrichtung in die Aufnahmebuchse ansteigenden widerhakenartigen Vorsprüngen ausgestattet, welche bewirken, daß das Tragteil lediglich unter Zuhilfenahme eines Hilfswerkzeuges wieder aus seiner Befestigungsposition abgenommen werden kann.Furthermore, from US-A-45 34 530 a supporting part for holding grid-like intermediate floors in the interior of a household refrigerator or freezer is proposed, the fastening pin of which is inserted in a receptacle inserted into an opening in the interior lining of the household refrigerator or freezer. For this purpose, the fastening pin is equipped with barb-like projections which rise in the receiving bushing counter to its direction of insertion, which have the effect that the supporting part can only be removed from its fastening position with the aid of an auxiliary tool.

Eine weitere Ausführungsart für ein Tragteil zur Halterung eines Verdampfers im Innenraum eines Kühlmöbels ist aus der FR-A-23 23 967 bekannt. Das daraus hervorgehende Tragteil weist ein Befestigungselement auf, welches in Art eines Bajonettverschlusses mit einer in die Wand des Innenraums des Kühlmöbels eingeformten Aufnahme verbindbar ist. Eine derartige Verbindungtechnik zur Befestigung eines Tragteiles im Innenraum eines Möbels eignet sich im wesentlichen nur für die einmalige Befestigung eines Verdampfers an der Wand eines Kältegeräte-lnnenraums, ist jedoch ungeeignet, wenn es darum geht, die Tragteile zur Abstützung der Zwischenböden im Rahmen einer Umgestaltung des Innenraums des Kühlmöbels möglichst rasch und auf einfache Weise aus der ursprünglichen Position in die gewünschte Position bringen zu können.Another embodiment for a supporting part for holding an evaporator in the interior of a refrigerator is known from FR-A-23 23 967. The resulting supporting part has a fastening element which can be connected in the manner of a bayonet lock to a receptacle molded into the wall of the interior of the refrigerated cabinet. Such a connection technique for attaching a support part in the interior of a piece of furniture is essentially only suitable for the one-time attachment of an evaporator to the wall of an interior of the refrigerator, but is unsuitable when it comes to supporting the intermediate floors as part of a redesign of the To be able to move the interior of the refrigerator as quickly and easily as possible from the original position into the desired position.

Der Erfindung liegt die Aufgabe zugrunde, ein Tragteil für in den Innenraum eines Möbels einbringbare Zwischenböden zu schaffen, das räumlich klein gebaut und in einem einzigen Montageschritt an den Wandungen des Innenraums, ohne diese durchbrechen zu müssen, befestigbar ist.The invention has for its object to provide a supporting part for in the interior of a piece of furniture can be made intermediate floors, which is compact and can be attached to the walls of the interior in a single assembly step without having to break through them.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß die Befestigungselemente in an die Innenverkleidung einstückig mitangeformte, als Höhlungen ausgebildete und zur Wärmeisolation hin abgeschlossene Aufnahmen einsteckbar sind, in welchen sie in Einsteckrichtung durch an den Befestigungselementen vorgesehenen Halterippen kraftschlüssig und ohne Unterstützung durch ein Hilfswerkzeug lösbar gehalten sind.This object is achieved according to the invention in that the fastening elements can be inserted into receptacles integrally formed on the inner lining, formed as cavities and closed for thermal insulation, in which they can be non-positively and without support by an auxiliary tool in the insertion direction by holding ribs provided on the fastening elements are held.

Durch die erfindungsgemäße Ausbildung der Aufnahmen ist aufgrund der nicht durchbrochenen Oberfläche der Wände des Innenraums auf einfache Weise sichergestellt, daß irgendwelche Stoffe aus dem Innenraum in die Wärmeisolation eintreten können oder aber Stoffe aus der Wärmeisolation in den Innenraum übertreten. Ferner hat die erfindungsgemäße Lösung den Vorteil, daß das Tragteil aufgrund seiner Befestigungsart baulich klein ausgeführt werden kann und somit ziemlich unauffällig im Innenraum eines Möbels anordenbar ist. Außerdem wird ein auf das Tragteil eingeleitetes Biegemoment durch die Anpassung der Konturen des Befestigungselementes und der Aufnahme und der dadurch lagerähnlich ausgebildeten Halterung zuverlässig ohne Beschädigung der beiden abgefangen. Darüberhinaus zeichnet sich diese Lösung dadurch aus, daß das Tragteil jederzeit lagestabil gehalten und trotzdem auf einfache Weise, ohne Unterstützung durch ein Hilfswerkzeug demontierbar und dadurch die Innenraumeinteilung eines Möbels entsprechend den Erfordernissen anpaßbar ist.The design of the receptacles according to the invention ensures in a simple manner, due to the uninterrupted surface of the walls of the interior, that any substances from the interior can enter the heat insulation or that substances from the heat insulation can enter the interior. Furthermore, the solution according to the invention has the advantage that the supporting part can be made structurally small due to its type of fastening and can therefore be arranged relatively inconspicuously in the interior of a piece of furniture. In addition, a bending moment initiated on the supporting part is reliably intercepted without damaging the two by adapting the contours of the fastening element and the receptacle and the holder which is designed like a bearing. In addition, this solution is characterized by the fact that the supporting part is held in a stable position at all times and yet can be dismantled in a simple manner without the aid of an auxiliary tool and the interior division of a piece of furniture can thus be adapted to the requirements.

Auf besonders einfache Weise lagestabil gehalten ist ein Befestigungselement, wenn nach einer bevorzugten Ausführungsform des Gegenstandes der Erfindung vorgesehen ist, daß als Befestigungselement ein Zapfen dient, der das Tragteil einerseits durch eine formschlüssige Verbindung gegen Verdrehung in der als an die Wand mitangeformte Aufnahme sichert und andererseits das Tragelement durch eine kraftschlüssige Verbindung zwischen ihm und der Aufnahme an der Wand hält.In a particularly simple manner, a fastening element is held in a stable manner if, according to a preferred embodiment of the object of the invention, it is provided that a pin serves as the fastening element, which on the one hand secures the supporting part against rotation in the receptacle which is molded onto the wall and on the other hand holds the support element by a non-positive connection between him and the receptacle on the wall.

Entsprechend einer weiteren vorteilhaften Ausgestaltung des Gegenstandes der Erfindung ist vorgesehen, daß die den Zapfen aufnehmende Aufnahme als ein an den Wandungen des Innenraums mitangeformter Napf ovalen Querschnitts ausgeführt ist, in den der Zapfen als Gegenstück dazu, keine vollflächige Lochleibung ausübend, eingeschoben ist.According to a further advantageous embodiment of the object of the invention, it is provided that the receptacle receiving the pin is designed as an oval cross-section molded onto the walls of the interior, into which the pin is inserted as a counterpart to it, without any full-surface perforation.

Unter Oval soll hier eine entlang einer Symmetrieachse gestreckte Fläche mit an den Enden gekrümmten Begrenzungslinien verstanden werden. Solche Flächengebilde können beispielsweise eine Ellipse oder zwei einander zugekehrte Halbkreise oder Halbellipsen mit einem dazwischenliegenden Rechteck oder eine eiförmige Fläche sein.Oval is understood here to mean a surface stretched along an axis of symmetry with boundary lines curved at the ends. Such fabrics can for example an ellipse or two semicircles facing each other or semi-ellipses with a rectangle in between or an egg-shaped surface.

Der Vorteil einer derartigen Lösung liegt darin, daß der Zapfen aufgrund der nicht vollflächigen Lochleibung ohne großen Kraftaufwand in die Höhlung eingeschoben werden kann.The advantage of such a solution is that the pin can be inserted into the cavity without great effort due to the imperfection of the hole.

Nach einer weiteren bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß an den Zapfen eine zu diesem senkrechte Wand anschließt, die mit einem Kraftspeicher ausgestattet ist, welcher in Richtung einer zu der Wand im wesentlichen senkrecht angeformten Tragfläche wirkt und im Falle eines darauf angeordneten Teils der Ablage auf diesen einwirkt.According to a further preferred embodiment of the subject matter of the invention, it is provided that a wall perpendicular to the pin is connected to the pin, which is equipped with an energy accumulator which acts in the direction of an airfoil which is substantially perpendicular to the wall and in the case of a part arranged thereon the shelf acts on it.

Einerseits zeichnet sich diese Lösung dadurch aus, daß die Wand als Anschlag für die Einschubtiefe des Zapfens in die Aufnahme dient und durch ihren Anschlag die lagerichtige Endstellung signalisiert, wobei sie zugleich dadurch die Aufnahme abdeckt, so daß eine Verschmutzung dieser vermieden wird. Andererseits bildet die Wand zusammen mit der senkrecht dazu angeformten Tragfläche eine in Form eines Winkelprofils ausgebildete, formstabile Auflage, mit deren Hilfe der auf ihr angeordnete Teil der Ablage sicher geführt und durch den Kraftspeicher zuverlässig auf ihr gehalten ist.On the one hand, this solution is characterized in that the wall serves as a stop for the insertion depth of the pin in the receptacle and signals the correct end position by its stop, which at the same time thereby covers the receptacle, so that contamination of the latter is avoided. On the other hand, the wall, together with the wing formed perpendicularly thereto, forms a dimensionally stable support in the form of an angular profile, with the aid of which the part of the shelf arranged on it is guided securely and is reliably held on it by the energy accumulator.

Gemäß einer weiteren vorteilhaften Ausgestaltung des Gegenstandes der Erfindung ist vorgesehen, daß der Kraftspeicher als im horizontalen Abstand voneinander angeordnete, mit einer Abwinkelung versehene Zungen ausgebildet ist, welche an der Wand mit von der Tragfläche abgewandter Zungenwurzel mitangeformt sind.According to a further advantageous embodiment of the subject matter of the invention, it is provided that the energy accumulator is designed as horizontally spaced, angled tongues which are formed on the wall with the tongue root facing away from the wing.

Neben einer preiswerten einfachen Herstellung des Tragteils hat dieses auch noch den Vorzug einer einstückigen Ausbildung, so daß die Montage und die Lagerhaltung dieses Tragteiles wesentlich vereinfacht ist.In addition to an inexpensive simple manufacture of the support part, this also has the advantage of a one-piece design, so that the assembly and storage of this support part is considerably simplified.

Nach einer weiteren bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß die Tragfläche des Tragteils in eine die Ablage in Einschubrichtung in den Innenraum und in Gegenrichtung dazu formschlüssig sichernde Ausnehmung des auf der Tragfläche aufliegenden Teils der Ablage eingreift, wobei in der Eingriffsstellung die formschlüssige Verbindung kraftschlüssig durch die federnden Zungen gesichert ist.According to a further preferred embodiment of the subject matter of the invention, it is provided that the support surface of the support part engages in a recess of the part of the support resting on the support surface in a form-locking manner in the insertion direction in the insertion direction and in the opposite direction, the positive connection in the engagement position is non-positively secured by the resilient tongues.

Der Vorzug einer solchen Lösung ist darin zu sehen, daß die Ablage auf einfache und zuverlässige Weise gegen unbeabsichtigtes Verschieben auf den Tragteilen sowohl in Einschubals auch in Gegenrichtung dazu gesichert ist. Außerdem werden auf die Ablage eingeleitete Kippmomente die ein Abheben der Ablage von der Tragfläche bewirken können, von den federnden Zungen je nach ihrer Dimensionierung, in gewissem Umfang abgefangen.The advantage of such a solution can be seen in the fact that the storage is secured in a simple and reliable manner against inadvertent movement on the supporting parts both in the insert and in the opposite direction. In addition, to a certain extent, the tilting moments initiated on the shelf, which can cause the shelf to be lifted off the wing, are intercepted by the resilient tongues, depending on their dimensions.

Ebenso wird eine Sicherung gegen Kippen bei einseitiger Belastung der Ablage erreicht, wenn nach einer anderen vorteilhaften Ausgestaltung des Gegenstandes der Erfindung vorgesehen ist, daß an den Zapfen eine zu diesem senkrechte Wand anschließt, die mit im parallelen Abstand voneinander angeordneten, im wesentlichen senkrecht von der Wand und entgegengesetzt zum Zapfen abzweigenden Platten versehen ist, die zwischen sich die Ablage aufnehmen, wobei die tieferliegende Platte als Tragfläche für die Ablage dient.Likewise, protection against tipping over one-sided loading of the tray is achieved if, according to another advantageous embodiment of the object of the invention, it is provided that a wall adjoins the pin, which is arranged at a parallel distance from one another, essentially perpendicular to the wall Wall and opposite to the pin branching plates is provided, which receive the tray between them, the lower-lying plate serves as a support surface for the tray.

Entsprechend einer weiteren bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß die Platten in Einschubrichtung der Ablage in den Innenraum einen die Einschubtiefe begrenzenden Anschlag aufweisen, der an die Platten mitangeformt ist.According to a further preferred embodiment of the object of the invention, it is provided that the plates have a stop limiting the insertion depth in the direction of insertion of the shelf into the interior, which is also molded onto the plates.

Durch eine derartige Lösung wird für den Fall, daß die Ablagen nicht auf eine andere Art fixiert sind, auf einfache Weise erreicht, daß bei mehreren übereinander angeordneten Ablagen diese zur Türöffnungsseite des Möbels hin in einer senkrechten Ebene fluchtend zueinander ausgerichtet sind. Außerdem wird bei einem Einsatz eines solchen Tragteiles in einem Kühlraum erreicht, daß die Ablage im Abstand zu dieser Rückwand angeordnet ist, so daß eine Luftzirkulation innerhalb des Kühlraumes gesichert ist.By means of such a solution, in the event that the shelves are not fixed in any other way, it is achieved in a simple manner that, in the case of a plurality of shelves arranged one above the other, these are aligned with one another in a vertical plane toward the door opening side of the furniture. In addition, when such a supporting part is used in a cold store, the shelf is arranged at a distance from this rear wall, so that air circulation within the cold store is ensured.

In einer weiteren bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß die tieferliegende der im parallelen Abstand zueinander angeordneten Platten auf der vom Anschlag abgewandten Seite verlängert gegenüber der höherliegenden Platte ist.In a further preferred embodiment of the subject matter of the invention, it is provided that the lower one of the plates, which are arranged at a parallel distance from one another, is extended on the side facing away from the stop relative to the higher plate.

Diese Lösung zeichnet sich dadurch aus, daß durch die Verlängerung der unteren Führungsbahn eine Einführhilfe für eine in das Tragteil einzuführende Tragplatte gebildet ist.This solution is characterized in that an insertion aid for a support plate to be inserted into the support part is formed by the extension of the lower guideway.

Besonders zweckmäßig angeordnet sind die Tragteile im Innenraum eines Möbels, wenn nach einer weiteren vorteilhaften Ausgestaltung des Gegenstandes der Erfindung vorgesehen ist, daß das mit den Federn der Zungen ausgestattete Tragteil im Bereich der Öffnung des Möbels angeordnet ist, während das andere mit den parallelen Führungsbahnen und dem Anschlag versehene Tragteil im Bereich der Rückwand des Möbels vorgesehen ist.The supporting parts are arranged particularly expediently in the interior of a piece of furniture if, according to a further advantageous embodiment of the object of the invention, it is provided that the supporting part equipped with the springs of the tongues is in the region of the opening of the piece of furniture is arranged, while the other supporting part provided with the parallel guideways and the stop is provided in the region of the rear wall of the piece of furniture.

Nach einer weiteren bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß die Aufnahmen an den Seitenwänden des Innenraumes über deren Höhe und deren Tiefe verteilt angeordnet sind, wobei die nicht von einem Tragteil belegten Aufnahmen durch mit der Oberfläche der Seitenwände nahezu bündig abschließende Verschlußstopfen abgedeckt sind.According to a further preferred embodiment of the object of the invention it is provided that the receptacles on the side walls of the interior are arranged distributed over their height and depth, the receptacles not occupied by a supporting part being covered by sealing plugs which are almost flush with the surface of the side walls .

Die Lösung entsprechend diesen Merkmalen hat den Vorzug, daß die nicht-benutzten Aufnahmen vor Verschmutzung gesichert sind, ohne daß die eingebrachten Verschlußstopfen störend wirken oder gar den zur Verfügung stehenden Innenraum einschränken.The solution according to these features has the advantage that the unused receptacles are secured against contamination, without the plugs inserted having a disruptive effect or even restricting the available interior space.

Die Erfindung ist in der nachfolgenden Beschreibung am Beispiel eines in der Zeichnung vereinfacht dargestellten Haushalts-Kühlschrankes erläutert.The invention is explained in the following description using the example of a household refrigerator shown in simplified form in the drawing.

Gemäß Fig. 1 ist ein Haushaltskühlschrank 10 dargestellt, der ein wärmeisoliertes Gehäuse 11 aufweist, dessen Innenraum durch einen durch Tiefziehen einer Kunststoffplatine erzeugten Kühlgutbehälter gebildet und mit einer Tür 12 verschließbar ist. Der Innenraum des Gehäuses 11 ist zum Abstellen von Kühlgut mit in unterschiedlichen Höhenlagen angeordneten, einzelne Fächer bildende Ablagen 13 ausgestattet, deren Ränder mit einem Rahmen 14 eingefaßt sind. In den einzelnen Höhenlagen sind die Ablagen 13 an den seitlichen, als Schenkel 15 ausgebildeten Abschnitten ihres sie umgebenden Rahmens 14 an weiter unten genauer erläuterten Tragteilen gestützt. Diese sind an den einander gegenüberliegenden Seitenwänden 16 des Innenraumes über dessen Höhe und Tiefe in jeweils gleichmäßigen Abständen verteilt, im Bereich des Öffnungsrandes bzw. im Bereich der Rückwand des Innenraumes in sackartigen Aufnahmen 17 gehaltert.1, a household refrigerator 10 is shown, which has a thermally insulated housing 11, the interior of which is formed by a refrigerated goods container produced by deep-drawing a plastic board and can be closed with a door 12. The interior of the housing 11 is provided for storing refrigerated goods with shelves 13 which are arranged at different heights and form individual compartments, the edges of which are bordered by a frame 14. In the individual heights, the shelves 13 are supported on the lateral sections of their frame 14 formed as legs 15 on supporting parts which are explained in more detail below. These are distributed on the opposite side walls 16 of the interior over its height and depth at equal intervals, held in bag-like receptacles 17 in the region of the opening edge or in the region of the rear wall of the interior.

Wie insb. aus Fig. 2 hervorgeht, sind die Aufnahmen 17 als an die Seitenwände 16 des Innenraumes mitangeformte - bei mittels Tiefziehen hergestellten Kühlgutbehältern mitangezogene - im Querschnitt ovale, als Näpfe ausgebildete Höhlungen ausgeführt, deren Tiefe durch eine Rückwand 18 begrenzt ist. In dieser Ausführungsform ist das Oval aus zwei einander zugekehrten Halbkreisen mit einem dazwischen liegenden Rechteck gebildet.As can be seen in particular from FIG. 2, the receptacles 17 are formed as cross-sectionally oval cavities in the form of cups, the depth of which is limited by a rear wall 18. In this embodiment, the oval is formed from two semicircles facing each other with a rectangle in between.

Die Aufnahmen 17 dienen zur Halterung von Tragteilen 20 und 40 die entsprechend ihrer Verwendung - im Bereich der Rückwand oder nahe der Öffnung des Innenraums - unterschiedlich ausgebildet sind, wobei die der Öffnung zugekehrten Tragteile mit 40 bezeichnet sind. Die Tragteile 20 sind auf ihrer den Seitenwänden 16 zugekehrten Seite mit einem als Befestigungselement ausgebildeten hohlen Zapfen 21 ausgestattet, dessen Außenkontur der Innenkontur der Aufnahmen 17 derart angepaßt ist, daß dieser einerseits reibschlüssig in die Aufnahmen 17 einschiebbar und andererseits durch den sich ergebenden Formschluß verdrehsicher an den Seitenwänden 16 gehaltert ist. Der als Hohlkörper ausgeführte Zapfen 21 weist auf der Innenseite seiner den Hohlraum eingrenzenden Wandung 22, parallel zur Längsachse des Zapfens 21 verlaufende, im Querschnitt rechteckförmig ausgeformte Längsnuten 23 auf, die unmittelbar übereinander in etwa in der Mitte der breiteren Abschnitte des ovalen Zapfens 21 angeordnet sind. Die Längsnuten 23, die über die gesamte Länge des Zapfens 21 angeordnet sind, erstrecken sich von der Innenseite der Wandung 22 bis nahe an deren Außenseite, so daß eine filmscharnierartige Wandstärke stehen bleibt. Durch eine solche Ausbildung des Zapfens 21 ist gewährleistet, daß die, die Aufnahmen 17 verkleinernden Toleranzabweichungen vom zapfen 21 aufgefangen werden können.The receptacles 17 serve to hold support parts 20 and 40 which, depending on their use - are designed differently - in the area of the rear wall or near the opening of the interior, the support parts facing the opening being designated by 40. The supporting parts 20 are provided on their side facing the side walls 16 with a hollow pin 21 designed as a fastening element, the outer contour of which is adapted to the inner contour of the receptacles 17 in such a way that it can be inserted frictionally into the receptacles 17 on the one hand and non-rotatably on the other hand due to the resulting positive connection the side walls 16 is supported. The pin 21, designed as a hollow body, has on the inside of its wall 22 defining the cavity, parallel to the longitudinal axis of the pin 21, rectangular grooves of rectangular cross section, which are arranged directly one above the other, approximately in the middle of the wider sections of the oval pin 21 . The longitudinal grooves 23, which are arranged over the entire length of the pin 21, extend from the inside of the wall 22 to close to the outside thereof, so that a wall hinge-like wall thickness remains. Such a design of the pin 21 ensures that the tolerance deviations that reduce the receptacles 17 can be absorbed by the pin 21.

Auf der Außenseite der Wandung 22 des Zapfens 21, ist mittig zu der höher liegenden Längsnut 23 eine im Querschnitt dreieckförmige, in Richtung der Längsnut 23 angeordnete Rippe 24 vorgesehen, die bis nahe an die der Aufnahme 17 zugekehrten Seite verläuft und als Klemmrippe dient, um eine vollflächige Lochleibung in der Aufnahme 17 zu vermeiden. Außerdem wird durch die Anordnung der Rippen 24 auf der durch die Längsnut 23 verminderten Wandstärke der Wandung 22 eine gewisse Elastizität der Klemmverbindung erreicht. Eine derartige Rippe 24 kann auch der tieferliegenden Längsnut 23 zugeordnet sein. Desgleichen ist es möglich, mehrere solcher Rippen 24 am Umfang des Zapfen 21 verteilt anzuordnen, wobei diese aber stets im Bereich der filmscharnierartig ausgebildeten Wandstärken liegen.On the outside of the wall 22 of the pin 21, a rib 24, which is triangular in cross-section and arranged in the direction of the longitudinal groove 23, is provided in the center of the higher longitudinal groove 23, which extends close to the side facing the receptacle 17 and serves as a clamping rib to avoid a full-surface reveal in the receptacle 17. In addition, the arrangement of the ribs 24 on the wall thickness of the wall 22 reduced by the longitudinal groove 23 achieves a certain elasticity of the clamping connection. Such a rib 24 can also be assigned to the deeper longitudinal groove 23. Likewise, it is possible to arrange a plurality of such ribs 24 distributed around the circumference of the pin 21, but these are always in the region of the wall hinge-like wall thicknesses.

Wie Fig. 2 zeigt, ist die der Aufnahme 17 abgekehrte Stirnseite des Zapfens 21 mit einer senkrecht zu dessen Längsachse angeordneten Wand 25 verbunden, die in Einbaulage des Tragteiles 20 als Anschlagfläche bezüglich der Seitenwände 16 dient und die Einstecktiefe des Zapfens 21 in die Aufnahme 17 begrenzt. Senkrecht von der Wand 25 zweigen zwei in Draufsicht trapezförmig ausgebildete, in parallelen Abstand zueinander angeordnete und einander gegenüber liegende Platten 26 und 27 ab, deren Basis mit der Wand 25 bündig abschließt. Die parallel einander zugewandten Platten 26 und 27 sind in etwa im Abstand der Höhe der Schenkel 15 des die Ablage 13 einfassenden Rahmens 14 angeordnet und nehmen diese zwischen sich auf, wobei die Innenseite der in Einbaulage des Tragteils 20 tiefer liegenden Platte 27 als Führungsbahn für die Ablage 13 dient. Außerdem ist die tiefer liegende Platte 27 mit einem in Einschubrichtung der Ablage 13 angeordneten Fortsatz 28 versehen, der gegenüber der höher liegenden Platte 26 vorsteht und als Einführhilfe für die zwischen den Platten 26 und 27 zu positionierende Ablage 13 dient.As shown in FIG. 2, the end face of the pin 21 facing away from the receptacle 17 is connected to a wall 25 arranged perpendicularly to its longitudinal axis, which in the installed position of the support part 20 serves as a stop surface with respect to the side walls 16 and the insertion depth of the pin 21 into the receptacle 17 limited. Two plates 26 and 27, which are trapezoidal in plan view, are arranged perpendicularly from the wall 25, the base of which is flush with the wall 25. The plates 26 and 27 facing each other in parallel are arranged approximately at a distance from the height of the legs 15 of the frame 14 enclosing the shelf 13 and take them between them, the inside of the plate 27 lying lower in the installed position of the supporting part 20 as a guideway for the Tray 13 is used. In addition, the lower-lying plate 27 is provided with an extension 28 arranged in the insertion direction of the shelf 13, which protrudes from the higher-lying plate 26 and serves as an insertion aid for the shelf 13 to be positioned between the plates 26 and 27.

Auf der den Fortsatz 28 gegenüber liegenden Stirnseite des Tragteils 20 sind die Platten 26 und 27 mit einer rechteckförmigen Stirnwand 29 abgeschlossen, die als Anschlag für die in das Tragteil 20 eingeschobene Ablage 13 ausgebildet ist. Im Abstand zu der Stirnwand 20, parallel zu deren längeren Seiten ist auf der Innenseite der höher liegenden Platte 26 in Richtung Fortsatz 28 ein im Querschnitt halbkreisförmiger Wulst 30 angeordnet, der bei eingeschobener Ablage 13 auf die ihm zugekehrte Seite des Schenkels 15 drückt und dadurch eine Art Klemmeffekt erzeugt.On the end face of the support part 20 opposite the extension 28, the plates 26 and 27 are closed with a rectangular end wall 29 which is designed as a stop for the shelf 13 inserted into the support part 20. At a distance from the end wall 20, parallel to the longer sides, on the inside of the higher plate 26 in the direction of the extension 28 there is a bead 30 which is semicircular in cross section and which, when the tray 13 is pushed in, presses on the side of the leg 15 facing it and thereby a Kind of clamping effect generated.

In Fig. 3 ist das bereits erwähnte Tragteil 40 dargestellt, dessen als Befestigungselement dienender Zapfen 21 identisch dem am Tragteil 20 angeordneten und bereits beschriebenen ist. An den Zapfen 21, senkrecht zu dessen Längsachse schließt sich auf seiner den Aufnahmen 18 abgewandten Stirnseite eine im wesentlichen T-förmig ausgebildetes Stützelement 41 an, dessen Steg als Tragfläche 42 dient und die zu ihm senkrecht angeordnete und mit dem Zapfen 21 verbundene Wand in zwei verschieden lange Abschnitte 43 und 44 unterteilt, wobei der Zapfen 21 hauptsächlich im Bereich des längeren Abschnitts 44 angeordnet ist. Über der Tragfläche 42, am freien Ende des längeren Abschnittes 44, an dessen seitlichen Rändern sind Kraftspeicher in Form von federnden Zungen 45 angeordnet, deren Wurzeln 46 an den längeren Abschnitt 44 mitangeformt sind. Die Körper der Zungen 45 weisen im wesentlichen zwei Zonen auf, von denen eine erste, länger ausgeführte, von deren Wurzeln 46 bis hin zu einer Krümmung 47, die in etwa auf der halben Höhe des längeren Abschnitts 44 liegt, geneigt zum Abschnitt 44 verläuft und einen spitzen Winkel zwischen sich und diesem einschließt. Die zweite Zone, die sich an die Krümmung 47 anschließt und sich bis hin zur Spitze 48 der Zungen 45 erstreckt, die mit Abstand über der Tragfläche 42 angeordnet ist, schließt einen stumpfen Winkel zwischen sich und der ersten Zone ein und ist zum längeren Abschnitt 44 hin abgewinkelt. Der längere Abschnitt 44 ist im Bereich um die Zungen 45, beginnend bei deren Wurzel 46 bis hin zur Tragfläche 42 mit einer als Federweg für die Zungen 45 dienenden Freisparung 49 ausgestattet, die eine Einfederung der Zungen 45 bei deren Belastung erlaubt.In Fig. 3, the already mentioned support member 40 is shown, the pin 21 serving as a fastening element identical to that arranged on the support member 20 and already described is. On the pin 21, perpendicular to its longitudinal axis, on its end facing away from the receptacles 18 there is a substantially T-shaped support element 41, the web of which serves as a supporting surface 42 and the wall arranged perpendicular to it and connected to the pin 21 in two sections 43 and 44 of different lengths divided, the pin 21 being arranged mainly in the region of the longer section 44. Above the wing 42, at the free end of the longer section 44, at its lateral edges, energy stores are arranged in the form of resilient tongues 45, the roots 46 of which are also molded onto the longer section 44. The bodies of the tongues 45 have essentially two zones, of which a first, longer, from the roots 46 to a curve 47, which is approximately half the height of the longer section 44, inclined to the section 44 and encloses an acute angle between itself and this. The second zone, which adjoins the curve 47 and extends to the tip 48 of the tongues 45, which is arranged at a distance above the wing 42, forms an obtuse angle between itself and the first zone and is to the longer section 44 angled towards. The longer section 44 is provided in the area around the tongues 45, starting at the root 46 up to the wing 42, with a recess 49 serving as spring travel for the tongues 45, which allows the tongues 45 to deflect when they are loaded.

Die Ablagen 13 liegen in Einbaulage mit den der Rückwand des Innenraums zugekehrten Abschnitten ihrer Schenkel 15 in der durch die Platten 26 und 27 gebildeten Führung, des im Bereich der Rückwand des Innenraums angeordneten Tragteils 20, wobei das der Rückwand zugeordnete Rahmenteil ihres Rahmens 14 an der Stirnwand 29 anschlägt. Die der Öffnung des Innenraumes zugeordneten Abschnitte des Rahmens 14 liegen in Einbaulage mit ihrer Unterseite an der Tragfläche 42 auf, wobei die Unterseite im Bereich ihrer Auflage an der Tragfläche mit einer in strichpunktierten Linien angedeuteten Aussparung 50 ausgestattet ist, in die die Tragfläche 42 bei aufliegender Unterseite eintaucht, so daß die Ablage 13 sowohl in Einschubrichtung in den Innenraum als auch in Gegenrichtung dazu formschlüssig gehalten ist. Die Aussparungen 50 sind an beiden Schenkeln 15 des die Ablage 13 einfassenden Rahmens 14 angeordnet, um die Ablage im Innenraum des Kühlgutbehälters zu dessen Seitenwänden 16 auszurichten und sicher zu halten.The trays 13 are in the installed position with the portions of their legs 15 facing the rear wall of the interior in the guide formed by the plates 26 and 27 of the support part 20 arranged in the region of the rear wall of the interior, the frame part of its frame 14 assigned to the rear wall being attached to the End wall 29 strikes. The sections of the frame 14 assigned to the opening of the interior lie in the installed position with their underside on the support surface 42, the underside in the region of their support on the support surface being provided with a cutout 50, indicated by dash-dotted lines, into which the support surface 42 lies when it is resting Immersed underside, so that the tray 13 is held positively both in the direction of insertion into the interior and in the opposite direction. The cutouts 50 are arranged on both legs 15 of the frame 14 enclosing the shelf 13 in order to align the shelf in the interior of the refrigerated goods container to the side walls 16 thereof and to hold it securely.

Zur weiteren Lagesicherung der Ablage 13 insb. gegen Abheben von der Tragfläche 42 wirken die am längeren Abschnitt 44 angeordneten federnden Zungen 45 auf die ihnen zugewandte Oberseite der beiden Schenkel 15 ein, wobei die Krümmung 47 oberhalb der Außenkante dieses Schenkelteils liegt, so daß die zweite, zum längeren Abschnitt 44 hin abgewinkelte Zone des Zungenkörpers gegen diese Kante drückt.To further secure the position of the shelf 13, in particular against lifting off from the supporting surface 42, the resilient tongues 45 arranged on the longer section 44 act on the upper side of the two legs 15 facing them, the curvature 47 above the outer edge this leg part lies so that the second zone of the tongue body, which is angled toward the longer section 44, presses against this edge.

Durch die sich aus der Krafteinleitung der Zunge 45 an der Ablage 13 ergebenden Kraftkomponenten wird diese einerseits in die Aussparung 50 gedrückt und andererseits werden auf der Ablage 13 einflußnehmende Breitentoleranzen insb. im Bereich der Öffnung des Innenraumes in gewissen Umfang ausgeglichen.Due to the force components of the tongue 45 on the shelf 13, the force components are pressed into the recess 50 on the one hand and, on the other hand, width tolerances influencing the shelf 13 are compensated to a certain extent, particularly in the area of the opening of the interior.

Der Abstand der Aufnahmen 17 für die Tragteile 20 von der Rückwand des Innenraumes ist so ausgelegt, daß der hintere Rahmenteil des Rahmens 15 der montierten Ablage 13 mit Abstand zur Rückwand, eine Luftzirkulation erlaubend, angeordnet ist.The distance between the receptacles 17 for the support parts 20 from the rear wall of the interior is designed so that the rear frame part of the frame 15 of the mounted shelf 13 is arranged at a distance from the rear wall, allowing air to circulate.

Die nicht mit Tragteilen 20 oder 40 belegten Aufnahmen 17 werden mit je einem nicht dargestellten Verschlußstopfen versehen, dessen Einsteckzapfen demjenigen der Tragteile entspricht und dessen daran angeordneten, die Aufnahmen 17 überdeckende Abdeckkappen sind mit einem Flachrundkopf ausgestattet.The receptacles 17 which are not occupied by support parts 20 or 40 are each provided with a sealing plug, not shown, the insertion pin of which corresponds to that of the support parts and the cover caps arranged thereon and covering the receptacles 17 are equipped with a pan head.
